1.1Safety precautions whenworkingon ve hicles with start-stop system
Whenworkingonvehicleswithstart/stopsystem,pleaseobserve the following instructions:
CAUTION
Risk of injury as a result of automatic engine start in vehicles with start/stop system.
♦In vehicles with the start/stop system activated (identifiable byanindicationinthedashpanelinsert)theenginecanstart automatically if required.
♦Make sure that the start-stop system is deactivated when carrying out work on the vehicle (switch ignition off, if nec essary switch ignition on again).
1.2Safety precautions during road tests in which testing and measuring equipment is used
Note the following if testers and measuring instruments have to be used during a road test:
WARNING
There is a risk of accident from deflection and insufficient se curing of testers and measuring instruments.
♦Using testers and measuring instruments during driving op eration causes distraction.
♦There is an increased risk of injury from unsecured testers and measuring instruments.
♦Always attach the testing and measurement equipment to the rear seat.
♦Always have the testing and measurement equipment op erated by a 2nd person.
♦Always operate the testing and measurement equipment from the rear seat.
♦Do not operate the testing and measurement equipment from the front passenger seat.
♦Persons can be injured by the release of the passenger air bag in the event of an accident.

♦Welding work using electric welding equipment may affect the ABS system.
♦Do the following before commencing welding work using elec trical welding tool:
–Disconnect the earth strap from the negative terminal of the battery and cover the negative terminal.
–Connect the earth connection of the electric welding tool di rectly to the part to be welded. There must not be any electri cally insulated parts between the earth connection and the welding point.
–Electroniccontrolunitsandelectricalwiringmustnottouchthe earth connection or the welding electrode.
♦During painting operations, the ABS control unit - J104may be exposed to a maximum temperature of 95 °C for only a short period, and to a maximum of 85 °C for longer periods (approx. 2 hours).
♦Do not drive the vehicle if the connector is unplugged from the ABS control unit - J104- .
♦Absolutecleanlinessisrequiredwhenworkingontheanti-lock brake system. It is not permitted to use any products which contain mineral oil, such as oils, greases etc.
♦Thoroughly clean connection points and the surrounding area before disconnecting, but do not use any aggressive cleaning agents, such as brake cleaner, petroleum, thinner or similar.
♦Place removed parts on a clean surface and cover.
